  <p>All of the C++ containers can be compared and assigned with the
  standard comparison operators: ==, !=, &lt;=, &gt;=, &lt;, &gt;, and
  =. Performing a comparison or assigning one multimap to another takes
  <a href="../complexity.html">linear time</a>.</p>

  <p>Two multimaps are equal if:</p>

  <ol>
    <li>Their size is the same, and</li>

    <li>Each member in location i in one multimap is equal to the the
    member in location i in the other multimap.</li>
  </ol>

  <p>Comparisons among multimaps are done lexicographically.</p>
